Bumper lights wiring question

[MichaelT333]

Hello all,
I was hoping someone with a little more understanding of electrical systems could help me out. So here’s my situation, when I reverse at night as I work early mornings, the reverse lights are not bright enough to see what’s behind me so I added a mini 6 inch light bar onto the rear bumper and wired it into my reverse lights. Everything went great works perfectly. I also have a six switch panel that I have installed in the place of the factory Mopar auxiliary switch optional upgrade and I want to be able to turn that light bar on with one of the switches if I chose to have it on while off-road. So my question is can I just splice the power wire and run it up to my switch panel? The reason I am asking is once I turn the switch on it will send power, not only to the light bar, but also down the splice and into the reverse light on the tail light. I don’t care if the reverse lights come on and stay on as well. My concern is, is it going to do any damage sending power the other way back up to whatever module controls, my reverse lights power? Thanks for the help.

I believe what you are looking for is a diode. A diode will make sure electricity only runs in one direction. As you said, you don’t want any kind of backfired.

How ever I can’t tell you what would happen if the switch panel is turned on and then you put it in reverse. Presumably double the voltage? Depending on the LED circuit it might be able to handle it or you might kill it.
